Hello and I hope someone can help
I have searched everywhere to try and solve this issue I have to no avail!
I installed xubuntu and my screen will only give default connection at 640x480
I have an output from xrandr-q
Failed to get size of gamma for output default
Screen 0: minimum 640x480 current 640x480 maximum 640x480
Default connected 640x480+0+0 0mm x0mm
640x480 73.00*
1024x768_60.00 (0x277) 63.500mhz -hsync +vsync
H: width 1024 start 1072 end 1176 total 1328 skew 0 clock 47.82khz
V: height 768 start 771 end 775 total 798 clock 59.92hz

Any ideas what to do to get 1024 ?
I have tried for days?
Thanks

Got the same problem here



Just installed Xubuntu 17.10
Main screen is working just fine in 1080p
second screen should be used in 1600x900, but I can only set it up to 1024x768
In second screen I use a passive MiniDP to DVI adapter. It always worked Fedora and Windows
AMD Radeon RX 280x

First of all, coinbr: you need to start your own thread. Mixing threads just causes confusion to everyone.
